AMALGAMATOR.

Application filed April 3, 1926.

This invention relates to amalgamators and more particularly an amalgamator especially designed for use in dental offices, the primary object of the invention being to I provide an amalgamator which will be substantially small, and one which may be operated by the usual dental engine, by attaching the device to the hand piece of the engine.

Another important object of the invention is to provide a rubber container for the metals under treatment, the construction of the device being such as to cause the same to be rapidly shaken, to accomplish the amalgamating result. I

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a side elevational view of an amalgamator constructed in accordance with the invention.

Figure 2 is a vertical sectional view therethrough.

Figure 3 is a sectional view taken on line 33 of Figure 2.

Referring to the drawing in detail, the device includes a hollow body portion 5 formed with a threaded opening disposed adjacent to the base 6 thereof, in which the bearing member 7 is secured.

The bearing member 7 acts as a support for the rotary shaft 8 that has connection with the usual flexible shaft of a dental engine, and may be connected with the shaft of the dental engine, by attaching the device to the usual hand piece of the dental engine.

Formed integral with the shaft 8 and disposed within the body portion 5 is a head 9 formed with an offset portion 10 adapted to contact with the lower end 11 of the rub ber container 12, during the rotation of the head.

This container 12 is substantially thick at the upper portion thereof so that it will fitclosely within the body portion 5 and be Serial No. 99,593.

held in an upright position by its contact with the walls thereof.

Positioned within the upper end of the container 12 is a closure 13 which is in the form of a stopper provided with a metallic flange 14: adapted to rest on the upper edge of the container 12, there being provided a finger piece 15 which may be gripped by the operator to remove the stopper and permit the metal to be treated, to be positioned therein.

In the use of the device, the mercury and alloy are positioned within the container 12 and the stopper 13, which is constructed to closely engage the surfaces of the container positioned within the container to close the upper end thereof.

The device is now positioned on the usual hand piece of a dental engine in such a way as to cause the shaft 8 to rotate rapidly with the result that the offset portion 10 of the head 9 will engage the lower end of the container 12 to shake the container 12 and cause an amalgamation of the metals positioned in the container.

After the amalgamating step has been completed the stopper may be removed and the metal removed from the container.

We claim:

1. In a device of the character described, a body portion. a flexible container supported within the body portion, a shaft extending into the body portion, a head on the shaft, said head adapted to engage the flexible container to shake the container when the shaft is rotated.

2. In a device of the character described, a body portion, a shaft extending into the body portion, a rubber container supported within the body portion and adapted to contain metal, and means on one end of the shaft to engage the rubber container to shake the container, and a removable plug for closing the container.

3. In a device of the character described, a hollow body portion, a container const-ructed of flexible material supported with- 1 in the body portion, a shaft extending into the body portion, means on one end of the shaft to engage the lower end of the container to shake material positioned within the container, and means for closing the con- 105 tainer.
